How can I access HttpContext Header values in Static class - static

Question

I am programming an ASP.NET Core 5.0 Web API.
I have a CurrentUser class like this. I want to access the header info anywhere in the project by using CurrentUser.Id. How can I do that? (or where can I initialize httpContext variable?)
public class CurrentUser
{
private static HttpContext _context;
private static UserDto _myUserObj;
public static void Initialize(AuthorizationFilterContext context)
{
_context = context.HttpContext;
_myUserObj = context.HttpContext.Request.Headers["User"] as UserDto;
}
public static int Id()
{
return _myUserObj.Id
}
}

I found some solutions. But I think its not best practice solutions. (There must be another and better way..)
MySolutions is that:
I am building a custom Attribute and i am adding it every API Controller like this:
[MyCustomAttribute]
public class UserController : ControllerBase{
//blablabla
}
After this : I am setting my CurrentUser.Initilaze() method in this Attribute like this:
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method)]
public class MyCustomAttribute: Attribute, IAuthorizationFilter
{
public void OnAuthorization(AuthorizationFilterContext context)
{
//fortest
var userObj = context.HttpContext.Request.Headers["User"];//working
var userObj2 = JsonSerializer.Deserialize<UserDto>(userObj, new JsonSerializerOptions()
{
PropertyNameCaseInsensitive = true
});//working
CurrentUser.Initialize(context);//working
var testResult = CurrentUser.Test();//working
}
}
So I can use CurrentUser static class everywhere in N-Layerd project and I am accessing UserId or another variables..
But i am saying again, I think its not best solution. Because I have to add [MyCustomAttribute] to all Controllers. There must be a better solition.
